Title
(EN) A FASTENER INSTALLATION TOOL
(FR) OUTIL D'INSTALLATION D'ELEMENTS DE FIXATION
Abstract
(EN)
In a fastener installation tool, return of a head piston (22) is effected by the application of air under pressure to the rear side of the piston. The end of the head cylinder body on the rear side of the piston is provided with a removable end member (34) which is displaceable away from a position in which it is safely secured to the head cylinder body (14). Also, the tool further includes a safety device in the form of air vent means (64) which, if the end member is displaced beyond a predetermined amount, opens to vent air under pressure from the head cylinder body on the rear side of the head piston (22), thereby preventing the return of the head piston and thus the further operation of the tool.
(FR)
Dans un outil d'installation d'éléments de fixation, le retour d'une tête (22) de piston s'effectue par l'action d'air sous pression sur le côté arrière du piston. L'extrémité du corps de la culasse du cylindre sur le côté arrière du piston comporte un élément d'extrémité amovible (34) qui peut être déplacé depuis une position dans laquelle il est tenu solidement au corps (14) de la culasse du cylindre. L'outil comporte également un dispositif de sécurité sous la forme d'un évent (64), qui s'ouvre lorsque l'élément d'extrémité se déplace au-delà d'une limite prédéterminée, pour laisser s'échapper l'air sous pression du corps de la culasse sur le côté arrière de la tête (22) du piston, ce qui empêche le retour de la tête du piston et donc le fonctionnement subséquent de l'outil.
